Refuse/oil removing device and refuse/oil recovery bag

Abstract

A refuse / oil removing device and a refuse / oil recovery bag are provided which can remove refuse and oil contained in drainage discharged from a restaurant in a simple manner without contact with the refuse and oil. A support base 46 of support means 40 is disposed in the interior of a grease trap 10 at a position higher than a water level 36b. A recovery bag 42 is attached to the support means 40 and plural layers of bag portions 68a, 68b, and 68c of the recovery bag 42 are put on the support base 46. The bag portions 68a, 68b, and 68c are each formed of a material which permits the adhesion of oil thereto and a large number of water passing holes 72 are formed in each of the bag portions 68a, 68b, and 68c. Drainage is introduced inside the innermost one of the plural layers of bag portions 68a, 68b, and 68c and is passed through the bag portions 68a, 68b, and 68c in this order, allowing refuse and oil to adhere to the bag portions. In this way the work of replacing the recovery bag 42 can be simplified and the amount of oil accumulated within the grease trap 10 can be decreased.

Description

TECHNICAL FIELD [0001] The present invention relates to a refuse / oil removing device for removing refuse and oil contained in drainage from restaurants, as well as a recovery bag for the recovery of such refuse and oil. BACKGROUND ART [0002] A large amount of refuse having shapes (e.g., food residues, toothpicks and skewers) and oil (sludge such as oil and fat) are mixed in drainage discharged from kitchens for business use such as those in restaurants wherein cooking and washing of tableware are performed frequently. When such refuse and oil flow through a sewer pipe, they adhere to the inner surface of the pipe and coagulate, with a consequent likelihood that the pipe diameter may be reduced or the pipe may be blocked. There also has been the problem that the environment, including rivers, is badly influenced by outflow of such refuse and oil into a public sewerage. [0003] For preventing the occurrence of the above problem, in restaurants and the like, a grease trap (Patent Docume...

AI Technical Summary

Benefits of technology

[0018] According to the present invention, by merely taking out the recovery bag from the support means, it is possible to remove refuse and a large amount of oil which, without the recovery bag, would be discharged into the grease trap. The work required is as simple as merely replacing the recovery bag. The work of removing refuse from residue and the work of cleaning a residue basket, which have so far been required, can be omitted. As a result, unpleasant works associated with the grease trap are no longer needed and hence it is possible to improve the rate of settling down of full-time and part-time workers in restaurants. Moreover, the bag portions of the recovery bag are positioned always above the water level in the grease trap and therefore, if the recovery bag is removed when there is no water within the bag portions, there no longer is any drop of water from the recovery bag nor is the hand stained with drainage. In the present invention, the movable member for attaching and detaching the recovery bag in the support means is movable relative to the leg portions and other portions, and by moving only the movable member without moving the whole of the support member, the recovery bag can be attached to and detached from the drain pipe and thus the recovery bag attaching and detaching work becomes very easy.

[0019] In the present invention, the bag portions of the recovery bag are formed as plural layers and are formed of a material which permits the adhesion of oil thereto. Thus, refuse and oil can be trapped by the plural layers of bag portions and most of oil discharged from discharge means toward the grease trap, as well as refuse adhered to the oil, can be trapped. As a result, not only the amount of oil accumulated in the second tank of the grease trap can be greatly diminished and the interval of the work for removing oil from the second tank can be greatly prolonged, but also the interval of cleaning within the grease trap can be prolonged and the cost of the cleaning work can be greatly decreased.

Problems solved by technology

When such refuse and oil flow through a sewer pipe, they adhere to the inner surface of the pipe and coagulate, with a consequent likelihood that the pipe diameter may be reduced or the pipe may be blocked.

There also has been the problem that the environment, including rivers, is badly influenced by outflow of such refuse and oil into a public sewerage.
